IMO IaaS is about flexibility and thus should provide bare metal (or
virtual bare metal) so that customers can use any OS they choose. OVF
seems to require this, since an OVF image can contain any OS; thus if
your IaaS claims to support OVF then you should be able to run *any*
OVF image containing *any* OS. I think this also requires full
virtualization since paravirtualization is neither standardized nor
widespread.
IaaS providers can provide optional prebuilt OS images, but it
shouldn't be part of the infrastructure.
